question regarding Striped RAID-0 SATA

Posted by: "Doug Yelmen" dougyelmen@earthlink.net   dougyelmen

i'd be buying the 1TB Striped RAID-0 SATA from OWC.
i know there are dangers with RAID setups. i wonder if
this is truly and plug and play situation, or are there things
i should know and be aware of. any help would be much
appreciated.

'Danger' in Raid setup? I assume you mean Raid 0 because Raid 1,5,6,10, etc
greatly decrease risk of data loss. Raid 0 double your chance of data
lost because the data is written across 2 drives (striped) so if either
drive fails all is lost. Raid 0 is used for speed and not data safety.

As far as setup - I have limited experience with OCW but if it says RAID 0
then I would assume it would be configured as such out of the box.

Hi Doug.

I'm certainly no expert on this subject, but I did recently install a two disk RAID-0 in my Mac Pro. I chose to install it internally because OWC said it would be faster. Just a few thoughts...

The drives need to be the same size, make, model and firmware so they play well together.

They split the data between two drives, so if you lose one drive, you lose all your data. Therefore a good backup is essential. I back up nightly to a single HDD using SuperDuper. Works great. I don't use Time Machine (maybe I should, but I don't).

Setting up the RAID internally is pretty easy using Disk Utility. Once set up, the computer sees the two RAID HDs as a single drive.

If you get an external RAID box, look at the features. Some support different RAID arrangements and some are more limited. Some are easy to switch between RAID schemes (striped, mirror, span, etc) and some are a bit more work. Also, some need the RAID arrangement to be configured via software and a few of them can't be configured using Lion (only OSX 10.6 or earlier).

I did buy an inexpensive RAID box from OWC for my two backup drives. It works with eSATA, FW800, FW400 and USB2.0. It can be configured as RAID 0/1/Span/Independent modes. You have to set a dip switch inside the case to set the configuration to what you want. Mine is currently set up in independent mode, so the two drives are seen as separate drives (plus they don't need to be identical in this mode). Here's the link to the box I use for my external backups.

I think I just told you everything I know about RAID!! Hope something here helps.

Lou

p.s. It did speed up LR4 a fair amount, at least on my machine.

Doug,

I sent a post previously, but it vanished into the ozone...perhaps I hit the wrong button.

Anyway, I'm no expert on RAID, but I did just install a RAID-0 in my Mac Pro. OWC said an internal RAID would be faster, so I installed two identical 2TB 7200 rpm 64MB cache SATA drives in Bays 2&3 of my Mac Pro. I used Disk Utility to set up the RAID-0 as one big partition and it worked fine. The computer sees it as a single big drive. The RAID-0 writes every file to both HDs simultaneously, which makes it a lot faster, but since every file is split between two drives, if one fails, you lose all your data. So, a solid backup is mandatory for safety.Some additional thoughts.

First, you need to make sure your drives are identical...same size, make, model and firmware. Apparently, it's not a good idea to set up a RAID 0 or 1 with drives that don't match, otherwise they may not play well together.

I did buy an external RAID enclose (no HDDs) since I had two internal drives that needed a home. This case will do RAID 0, 1, Span and Independent modes. Since the two HDDs I installed are not matching drives, I set them up using Independent mode, so the computer sees them as two independent drives. Only a single cable is required to access both drives. There is a dip switch inside the RAID box that selects the desired RAID mode. I'm using this to back up my OS/Programs drive and my Data HD (data is on my RAID drive). I'm using FW800, which is plenty fast since it is only for backup, and I do incremental backups with SuperDuper, which is fast.

Different external RAID boxes have different features. Make sure it supports the connections you want (USB 2/3, FW400/800, eSATA, etc). Also, some external boxes are only software configurable and a few of them can't be configured with Lion (need 10.6 or earlier), so watch out for that. Others have switches, etc, and most the ones I saw come preconfigured as RAID-0. The more you pay, the more features and flexibility you get.

My read and write speeds increased about 3X over my previous HDD setup using the internal RAID-0, (checked with SpeedTools) and this definitely made LightRoom 4.1 run faster.

I back up using SuperDuper, and it works great. I have it scheduled every night at 1:00AM, and SuperDuper sees my RAID as a single Volume and copies to my external drive just fine. Same with my OS/Programs (on an SSD) to external backup.

Here's the external enclosure I purchased. It's quiet, well built and seems to work fine. I may change to a different RAID mode some time in the future, but for now, Independent mode works for me.
http://eshop.macsales.com/item/Other%20World%20Computing/MEPQ946QL2K/

Hope something here helps (and I hope this post makes it to the forum this time).

thanks, Dane. i knew that. yes, i thought i said RAID 0 for speed.
and i learned from OWC that if one drive fails, all data will be lost.
dang.
OWC said it was alright right out of the box. like you said.

i tried a mirrored RAID once, and didn't follow instructions. i had to install a new PCI card. harrrrrrrrrrrr.

thanks, Dane.

a backup. i didn't know i could do that. a nightly. i can handle that. i have never used Time Machine, doubt i ever will.
i have four OWC Quad externals, and one with 1TB of storage for my photography. i guess i could partition that and back up the RAID nightly to it. that solves a LOT of problems. i am saving your email, to look at it later, figure out what i don't know. and see if it is relevant to the the RAID performance. i think i will just get the 1 TB. i don't take that many photos.
i bought a iMac. seems everybody was telling me it would be enough. but, i went from a G5 where i could upgrade everything, and have 4 drives. well, maybe next time.
i think i will go with this one: http://eshop.macsales.com/shop/firewire/1394/USB/EliteAL/PerformanceRAID

as for HTHs ABsolutely does.
thanks.
i am getting excited. i love tinkering.

my iMac has super powers, and grabbed your previous post from the ozone.

the drives come from OWC, so everything will be copacetic. no worries.
but, i WILL back it up nightly. i switched back to CCC. no worries.

it made it to the forum.

i maybe reinstall SD! if i have any problems with CCC, which i doubt.

i am loving my 120 GB SSD.

i might just buy it this week.

Doug,

That looks like the same exact box I bought, but I bought mine without drives (I had two drives that I took out of my Mac Pro and put them into the box). I think you'll like it.

Yes, I do a "smart" incremental backup nightly with SuperDuper and it clones both my OS and data drives to the backup drives in the box. I can boot from the cloned OS drive no problem, so I know it works.

Just want to make sure you know that a 1TB RAID-0 uses two 500GB drives (storage size is additive with RAID-0, unlike a RAID-1 where 1TB + 1TB = 1TB).

I'm a photographer, so let me know if I can be of any help.

Presumably you are talking about the OWC Elite Pro RAID externals? I use quite a few of these. They are designed for high performance, primarily for video editors (like me). I like the OWC's as much as anyones RAID 0 externals. Alternatives are GRaid (good) and LaCie (don't go there) and many other smaller high (ProMax) and low end venders.

Yes, these are simple plug and play drives. They behave like any other external. They are simply faster.

That is presuming you are talking about the Elite Pro's. OWC does sell configurable arrays. Also likely to be plug and play out of the box, but can be configured. The Elite Pro's are "hardware" RAIDs. They are not configurable.

Remember, RAID 0 is entirely about speed. It actually decreases security by half as there are now three failure points rather than one (two drives and the RAID itself). Drive recovery utilities do not work or RAID 0 drives though Disk Utility works fine at the high level.

If you need speed and security, consider RAID 0+1 (OWC has this too) or RAID 5.

Cheers,

Doug,

Cool. Let me know how you like your RAID and how it affects performance. I'm especially interested in your feedback on how it impacts LightRoom 4.1 performance.

Sigh .... Another problem I know nothing about. Quite suddenly, without my knowingly doing anything to change it, the text on my computer isn't as clear as it was yesterday and it's wider than normal. Not lots wider, but wider, none the less. About an hour ago when I left the computer, when I came back, it was off (both computers -- have two hooked up to one monitor) but nothing else in the house had turned off. So I powered them both back up and all seemed fine. I'm using a Mac Mini (new about 3 mos ago) and a G4.

What can I do to change the appearance of the text? It's not horrible, but I'm used to its being very clear.

Check your display setting under system prefs.

You had a momentary power outage. Computers are more sensitive to it than most of your other electronics. I take it you do not have a UPS or uninterruptible power source between your computer and the wall plug.

BTW printers, especially laser printers, refrigerators, freezers and A/C units are horrible about creating power surges and power drops. Do not plug your printer into the UPS with the computer, and try to keep the computer away from circuits that have any of these appliances on them, even if they are in another room.

You say the text is wider. Maybe you switched display resolutions. Have a look at System Preferences/Displays, then choose the Display tab, and try other resolutions. See if there is one that returns you to normal.

Amazingly, when I came back to the computer after a few hours, everything was back to normal. I think I have a ghost living in my house who's messing with my computer. Things keep changing that I didn't change. Yesterday my sound was gone and people in this group suggested the sound might be on mute in System Pref and sure enough, it was, but I hadn't changed it. Then today the sound was off AGAIN and when I looked, the sound was on mute again. I've had this computer about 3 months (Mac Mini) and nothing like this has ever happened. Just weird!!

Quite suddenly, without my knowingly doing anything to change it, the text on my computer isn't as clear as it was yesterday and it's wider than normal. Not lots wider, but wider, none the less. About an hour ago when I left the computer, when I came back, it was off (both computers -- have two hooked up to one monitor) but nothing else in the house had turned off. So I powered them both back up and all seemed fine. I'm using a Mac Mini (new about 3 mos ago) and a G4.

I think you might have hit screen zoom (Option Command =) without
realising. Try it now and see if it looks like it. Option Command - (minus)
to zoom back out.

You can also zoom using the scroll button on a mouse or a trackpad.

It might be good idea to have a look in System Preferences > Universal
Access > Seeing and Keyboard & Mouse to see what is *possible* and what the
shortcuts are.

Hello,

Randy mentioned a lot of systems including one at source forge. Thanks Randy.

Some government stuff from the EPA [Wiki for CAMEO]
MARPLOT [Part of CAMEO, so you can map disasters with disaster simulations
like ALOHA....:)]
MARPLOT is a Macintosh (and PC) program but the entire CAMEO suite of disaster
management and mapping was created on the Macintosh. Probably one of the
better user friendly systems with extensive mapping and GIS type features [but
not game quality graphics]. Minimal assembly required in the sense that it is
an advanced system. Try it. Once you got this one, you can proceed to the
below.....

If you want a Geographic Information System (GIS) you have to be able to
integrate generic components [Xcode, Make,...].

Theoretically, there are some high powered systems for the Mac [I.E., UNIX or
ports to the Mac]. Wiki for the following keywords. Analyze. Then Google for
the keywords to see if you get supplementary links. Might want to wiki for the
keywords just for background information. The wiki articles have great links.
Look for links that start with the phrase "List of".

GIS
Map projections [Mercator,...]
UTM
Open Geospatial Consortium
WMS
Open Street Maps
USGS
Web3D consortium [anything web3d, but look for geo type stuff like
geovrml,...] (Web services mapping other than Google and Bing)
GRASS [Extremely high powered system for the Mac. GRASS is free and powerful,
but sort of the like Red Hat Linux business model. Red Hat will sell you ease
and convienience. Same with "useful" GRASS user interfaces].
ESRI [ recently produced a Mac product so may be of limited utility ] (ESRI is
one of the big dogs in GIS)
PostgreSQL [PostGIS, GEOS, PROJ.4], Apache Ant, GDAL (UNIX GEEK STUFF)

Some government stuff from NASA [nasa.gov]
NASA Worldwind (probably have to get the source, separate out the rendering
component and roll your own Cocoa interface)
NASA has probably some other cool mapping stuff

All GIS's are mapping systems on steroids.

Note: GRASS is technically, the big dog for open or quasi open source GIS for
the Mac. However, if ESRI starts making more Mac stuff, the Mac has hit the
jackpot.

Hello,

Cleaning out my email.

Remember the Roman Roads email post by Moortgat in May.....

It's a web services mapping for historical cartography. However, it is an
example of a web service that has a lot of general background on general
cartography and mapping.

Apple has slowly been drastically improving security on the Macintosh
with the last few releases of OS X. With the release of Mountain
Lion, there will again be more increases. Some of these may be
distressing to users, especially Apple's use of the Mac App Store to
serve as a safe haven for software that has been tested to be free of
malware, and the ability of Mountain Lion to be set only to run
software downloaded from the Mac App Store.

Here is an excellent article on upcoming new security features and
their potential ramifications:

I thought I was already my system gatekeeper when I am asked: Do I want to open this application I have just downloaded?

Exploring looks like the last thing Apple wants us to do anymore. As long as I have my friend "Little Snitch 2.4" running constantly, I feel fairly safe.

Little Snitch allows me to run some amazing things on my Mac. jr

Howdy.

Someone asked about GPS map apps.

Check Skobbler. German company. GPS. Turn by turn. Voice. Maps.

I have a friend who likes it.

Unable to create sparse disk image

Posted by: "Robert" cookrd1@discoveryowners.com   cookrd1

Tue Jun 26, 2012 7:35 pm (PDT)



I have Lion on my MBP. 1 TB spinning hard drive formatted into three partitions (SL and Lion are both OS X journaled, third partition is NTFS).

I am trying to create an encrypted sparse disk image. I tried on all three of the partitions and get an error Unable to create named.sparsediskimage. Resource busy.

I tried unmounting the SL or the NTFS drives and that didn't help.

I searched on how to do this and am following all the instructions, but something is not right. Can anyone help?
Thanks
Bob
